Official Skynetic 1000mm Havok Racer Thread

[TaSaJaRa]

I have done about a 50-70% throttle with a 4s 3000mAh no issues for me other than hitting a tree limb in one of my flights.
Kept on flying, just had a pretty good ding in the middle of the wing. Sorry for the shaky friend was using my cell phone to record

[Aros]

Good job! Sorry I missed your other post...I would have recommended half throttle...Broke a few props when I was first learning how she likes to be launched. I also replaced the stock (brittle) props with APC props. MUCH better!

[Coastiehelimech]

Ok. After Zero input from this forum i decided to push my 4s 2200 mah all the way forward to firewall. Checked the CG and was slightly nose heavy. No problem. Swapped everything over to a replacement fuselage, recalibrated the AR631.

Headed to the fly field. Winds were blowing 10-15kts.
Gyro off, 45*hand launch. This time with 45% throttle, no torque roll!

She flys great! Super fast.

Love it.

[Coastiehelimech]

Ok. Here goes. Bought a V900 and after 4 failed hand launches and repairs I discovered the Havok.

Great! Looks good, nice price. I bought one and build according the instructions. I installed an AR631 gyro set up with 3 FM (safe select) Self leveling, bank angle limited, and OFF.

Set CG to instructions and didn't see ANYTHING about dual rate or expo settings so I didn't add that.

Maiden flight,4s 2200mah, All gyro modes OFF, 70% power, hand throw at 45*. Torque roll and inverted in 2 sec at 10 feet altitude. Countered with alieron input and throttle off , aircraft rights itself but roll rates are extremely touchy, altitude now 2 feet, flip gyro to self level and punch throttle. Aircraft recovers. Whoo!

Landing was straight forward but fast.

Battery #2

Ok. You got this, I decided to use gyro on but only bank limits (60* ) since I dont want gyro to level off right away.

60% throttle this time and 45* hand launch, again roll rate extremely hard to control. Torque roll present, already too low to chop throttle I punch it. It lawn darts in the grass field to the point the spinner is 3" under ground. Took 2 hands to pull aircraft out. Never had that happen to my rc planes..WTF!

Waiting for replacement fuselage to arrive. Good news no damage to wings.

Questions:

should I hand launch with 50% throttle to removed torque roll or is that not enough power? 4s 2200mah weight onboard.

Should I try hand launch with self leveling ON? Or would torque roll still happen?

What expo and dual rates should i program and use at launch?

it flies nice, but the uncertainty of torque roll on launch has me ready to go back to rc helis..

Thanks.

Glad to see that this model is again AVAILABLE .......also glad that it appears that a 5S 2200 could be strapped inside..!

Called Motion today since the Skynetic Havok is available in Europe and wanted to know if they are on the way to the USA. The person I spoke to said yes but really could not be accurate at all about when. I prefer my EFXtra over my EFX racer. Flew them both today. I would love to give the Skynetic Havok a try as well.

[Aerobatic Addict]

I still fly all my EFXtras and I just gave away the EFX racer I had still flying my V-900 and my Skynetic Havoc. Once I started flying the new V-1200 I have parked all the others. I hate hand launching and belly landing. Now when I go to fly I always have my V-1200 with. This plane beats them all hands down

Yes I have seen 3 guys flying the V1200 and love it. I wish they had not made it the same colors as the sky. I do like the idea of the low cost belly landers that can land any way with the wind. I did get to fly a v1200 and was impressed. It snapped much better than my v900 ever did.

[Skosh25]

Once it does come back in stock, I think I'm going to buy two this time. I had a V1200 and sold it. Still prefer the Havok.

Here is a clip from a couple of us racing.

The EFXtras don’t play well with others. Here is a V900 that my racer took out mid flight. We think my main wing broke off his vertical stab mid race.

[Double E]

We’ve got a group of guys flying the EFX and EFXtra Racers at our local field. I picked up a used Havok when HK was out of stock on the EFXtras. My guess is that the EFXtra and Havok are likely coming out of the same factory. The packaging and graphics are pretty similar. My hope was that the Havok would hang with or outperform the EFXtras that we fly on 5s with stock 60amp ESC and 7” prop.

The KV on the Havok motor is lower so I would assume it would be slower on the same prop and battery setup. I static tested an APC 7x8 sport prop on 5s and it produced over 1400 watts. At the field the Havoc appeared to be 5-10mph faster on level flight. During the third race, the motor smoked. No replacements available at Motion.

I grabbed one of the motors from a crashed EFXtra and it has the exact same prop adaptor hole spacing. The only issue is that the EFXtra motor is shorter than the Havok motor. I used two of the EFXtra motor plates to space it out perfectly. I put a 7x7 APC sport prop on it and it didn’t disappoint. Didn’t get to race it against one of the EFXtras but I think it would hang.

My one observation is that the dihedral on the wings seems exaggerated compared to the relatively straight wing of the EFXtra. On a positive note, the Havok wing seems a little thinner and less draggy that the EFXtra.

The EFXtra and Havok are some of the best racers money can buy for $150. Tons of fun racing with a group on 5s.

Hope Motion gets the Havok and parts back in stock.

Would love to see this back in stock. I have had and liked many EFX racers and a few EFXtras. I had the V900 but did not like it. I would like to give this plane a try. I also would like to see a bigger version to compete with the V1200 with retractable gear and flaps that can fly on 6s 5000. That would be really cool!

ARE WE GOING TO SEE NEW STOCK OF THIS RACER IN 2021.......or do we have to wait until COVID is over..!

[AceMigKiller]

Always sucks when you can't lock in a cause.
Sorry to see that!

[mr.frankenjet]

bummer, sorry abut that, hopefully new ones will come online soon

[Skosh25]

Well, I crashed my beloved Havok last night. No idea what happened. I was on the last flight of the evening with 2 minutes battery left. Completely lost signal. Post-mortem bench testing revealed no anomolies with the battery, all servos worked normally, linkages & control surfaces intact and secure. Futaba receiver. Impressive it didn't do more damage- went straight in. In fact should be flyable again with a new fuse. I'd probably replace the motor too, even though it turned over fine in bench testing. Or at this price point I may just buy a new model all together.

Only thing I can think of is signal interference or possible ESC overheat. But i've pushed it harder in the past with no issue and ambient temps were in the 60's.

Sure wish I knew an ETA for when they'll be in stock again. I got a good 50+ flights on her with no issues prior to this.

I love APC props, I used them as upgrade props for my FW 850mm P-51. World of difference.

+1, allot more efficient and quiet, not sure why so many planes come with thick butter knife looking props,APC is a cheap upgrade

[mr.frankenjet]

the apc props come with multiple adapters that fit at the motor side of the prop, this area stays square on the shaft as it's untouched by the reamer. While a prop reamer is a good choice the tapered version works and centers perfectly if you work side to side carefully,might be even better as you can get a really snug fit upfront. I have done too many props to count in this way and they all spin smooth as silk after balancing. Just put a new 8x6e on, I had just tried the gas version as the increased thickness makes it a bit more robust but it felt a bit slower and less efficient as expected. Added some additional ale reflex for my air break set up for the next outing, this works really well.

[Wild Man]

Make sure you get the right one they have two, the standard SAE and the Metric Reamer's
